I put ngk iridium ix plugs in my 1998 escort lx 2.0 SOHC about a month ago. I bought the plugs because i read iridium plugs last awhile and work very well. I also put new ignition autolite ignition wires on when i upgraded the plugs. The other day i had a misfiring problem and the ignition coil went bad. The car runs now with the new coil, the old one had a crack over top the electrical connector. About 5 months ago i had to remove the iginition coil from the mount to get to my thermostat, and maybe thats when the crack happened and i didnt notice. Anyway, i was just wondering if i need some special wires for performance plugs or anything like that?
